Question about 1994 GMC Safari
The engine goes from smooth idle to small rough idle.I have replaced fuel pump,plugs and wires,most sensors,adjusted timing,filters. The engine will run real smooth for one day,rough the next. (please help)
Im not sure if you got it fixed yet! It could possibly be idle air control valve. But here some more suggestions! I had a 94 Safari van 4.3 liter I was working on for about three days and I finally figured out what was wrong with it. It would run fine for a couple minutes and as soon as I hit the gas and let off it would surge, but anyways I ended up changing the distributer, after the fuel pump and filter, mass air flow sensor, egr valve, idle air control valve, map sensor, and ignition module. So that might sove the problem if you were on the same track with it as I was. Hope this helps ya!
